When the seminaries became bath houses for priests who had absolutely no intention of conducting themselves with chastity or morally, then it became a mess. Straight priests were treated poorly and finally retreated to being single or taking a wife, instead of serving the Body of Christ through the Mass.
Let's see how this goes, but somehow I can't imagine the military would enforce moral and ethical guidelines more successfully if the ratio of gays to straights becomes unbalanced. I don't care HOW disciplined they think they are. A few bad apples placed in the wrong rank, or the wrong guy has a pass made and this could go amazingly awry. Whether you want to proudly state you're gay...whatever.
Dont ask Don’t tell already accomplishes what you are suggesting. Unlike Catholic priest we are subject to the UCMJ which until now has criminialized such activity.
